We revisit the deļ¬nition of unforgeability of blind signatures as proposed by Pointcheval and Stern (Journal of Cryptology 2000). Surprisingly, we show that this established deļ¬...
An easy to follow tutorial that covers the implementation details of the Narrow Band Level Set Method. It also covers the numerical approximation for PDEs governing different types...
Abstractā Spam has been a serious problem for email causing frustration and annoyances to customers. This problem is growing at a fast rate with no signs of abating. Another form...
We propose GMSS, a new variant of the Merkle signature scheme. GMSS is the ļ¬rst Merkle-type signature scheme that allows a cryptographically unlimited (280 ) number of documents ...

Recently, a mathematical proof is obtained in (Liu, Chiu, Xu, 2004) on the so called one-bit-matching conjecture that all the sources can be separated as long as there is an one-to...
